• Answer:

  its a good thing that you asked this question twice because I would not have been able to answer again else. even though you can not leave without your fathers permission, you can obviously get a visa which you have said that you already have, you asked in another question if while on holiday in the UK you could run to the US embassy, is your family really planning on a holiday in the UK because if so you could just run away from them and start making applications for citizenship as you would be quite legal to stay with your visa. do you know how to go about making aplications for citizensip?
